Looking for an excuse to try out Metro's extended Red Line? Take it to the Catholic (7-3) and Navy (9-1) women's basketball game at McDonough Gymnasium, tomorrow night at 6 o'clock.

It will be the preliminary game to the men's 8 p.m. match between the Midshipmen and the Cardinals. The women's game should end in time for the subway rider to catch one of the last trains out of the Brookland station and head for home.

Catholic's coach Marie Wiles said of the Mids, "I think we can take them. George Washington beat them by one in Annapolis and we had no trouble with GW (in an 86-51 win)."

Navy women's coach Dave Smalley thinks the game will give him "an indication of how much our program has to improve." When told of the margin in Catholic's win over George Washington, Smalley laughed. "We'll have our hands full, I guess," he said.

Catholic has a height advantage with two 5-foot-11 freshmen: Sharon Hodges, a graduate of Holy Cross Academy's No. 1-ranked 1976-77 girls team, and Margaret Goetze, who led Oxon Hill to the Maryland State finals in 1976 and 1977.
